Abstract

This study is intended to propose a new method for explicit analysis of surface defects using Computer Aided Deduction (CAD) system. In this investigation an intelligent scheme is proposed to perform the filtering process in the preprocessing stage by using Proposed Hybrid Gaussian Filter (PHGF). Manual quality control is always associated with a certain degree of variation in both throughput and accuracy an automated vision system can improve both of these significantly and this study aims to develop such a computer aided system for the specific application for surface defect detection in the laser hardfaced surface of Stellite-6. In this work the microstructure images of Stellite-6 Laser Hardfaced samples have been investigated. In this phase, Scanned Electron Microscopic (SEM) image is acquired and noises from those images are removed using Proposed Hybrid Gaussian Filter (PHGF). Which performs the three-step ranking operation from different spatial directions on the image data that offers higher Peak Signal to Noise Ratio (PSNR) value of 50.007dB and lower the Mean Square Error (MSE) value of 11.796. The performance results show that the Proposed Hybrid Gaussian Filter (PHGF) outcomes better results compare to Mean filter, Median filter, Wiener filter and Gaussian filter, in terms of Mean Square Error (MSE), Mean Absolute Error (MAE), Peak Signal to Noise Ratio (PSNR), Entropy-1, Entropy-2 and Image Enhancement Factor (IEF). This analysis helps to select the filter and best combination of process parameters along with the less surface defects.
